城镇化进程中城市防灾避险绿地系统构建——以梁山县中心城区为例

Construction of Urban Disaster Prevention and Avoidance Green Space System in the Process of Urbanization—Taking the Central Urban Area of Liangshan County as an Example

摘要: 现代化城市进程下，县域经济与生态发展不协调，城市抵御突发性灾害的能力较弱。城市绿地在城市系统中承担了部分防灾避险功能。研究以济宁市梁山县中心城区为例开展实地调研，结果表明：城区现状绿地比例过小，缺少公共绿地以及开敞空间，绿地系统并未形成。通过对梁山县城区防灾避险绿地的适宜性评价，结合城市空间分析，从提升绿地率、形成单元绿地以及绿地避险系统化3个方面构建中心城区防灾避险绿地系统。

Abstract: In the process of modern urbanization, the county economy and ecological development are not coordinated, and the city’s ability to resist sudden disasters is weak. Urban green spaces play a part in disaster prevention and refuge functions within the urban system. This study conducted a field investigation in the central urban area of Liangshan County, Jining City, and the results show that the current green space ratio in the urban area is too small, lacking public green spaces and open spaces, and the green space system has not been formed. By evaluating the suitability of green spaces for disaster prevention and refuge in Liangshan County’s urban area, combined with urban spatial analysis, the study constructs a disaster prevention and refuge green space system in the central urban area from three aspects: increasing the green space ratio, forming unit green spaces, and systematizing green space refuge.
